United States Patent 3,199,213 GUIDE SYSTEM FOR THE MOVING PORTION OF A ONE-COLUMN PRESS Albino Fen-anti, Viale Marche 97, Milan, Italy Filed Oct. 13, 1951, Ser. No. 144,916 3 Claims. (Cl. IMF-214) This invention intends'to provide a simple and efii- V cient one-column press.

The guide system according to the invention cornprises, in combination with a generally upright frame member, a prismatic head supportedin cantilever fashion on the upper end thereof and provided, on at least a part of its outer wall surface, with guides for the movable press portion. The movable press portion includes a prismatic coring, rigid with the platen and rising above the latter, Whose inner walls are formed with guide surfaces designed to co-operate with the complementary guide surfaces carried by the prismatic head received within the casing.

The invention will now be disclosed more fully in the following description, taken with the accompan ing drawing wherein an embodiment of the guide system according to the invention, as fitted on a hydraulic press, is shown.

in the drawing:

FIG. 1 is a perspective view of the press;

FIG. 2 is a side-elevational view, partly in section of the upper portion of the press wherein the guides are fitted;

FIG. 3 is a plan view of the press, with some of the components shown partly in section; and

FIG. 4 is a cross-sectional view along the line IVIV of FIG. 3. 7

As shown in the above figures, the main frame of the press comprises a base A for the stationary bottom plate or bed 14, a C-fr-ame B, and an upright C, forming the press column.

The above structure is more detailedly described and illustrated in my copending application Ser. No. 144,717 filed October 12, 1961, now abandoned.

The upright C consists of two-prismatic posts 34, 36

positioned and firmly secured on both sides of C-frame B. A box-shaped head D is secured at the upper end of said upright and is formed by an upper plate 23, by a bottom plate 3t) and end plates 32, 33.

Head D has a prismatic shape and vertical edges of its front portion have projecting rectangular corner formations 48 which, together'with the upper extremities of upright posts 34, 36, formed fixed guide surfaces for the movable portion of the press. I

The movable press portion comprises a prismatically shaped casing F, within which the" head D is accornmodated, and a plate 5%, or movable platen, fitted at the bottom of said casing. The casing is formed with side walls 52 and a front wall 54. Right-angled corners are formed by orthogonally adjoining strips 55, 58 along the vertical inner edges of said walls and receive the previously described rectangular formations 48, thereby forming a part of the guides for the movable casing F. Walls 52 are reinforced by outer ribs 53 which ex- 7 3,i@,2l3 Patented June 22, 1965 ice casing F.

- Bosses 60 and .62 FIGS. 1 and 2 are formed along the vertical outer edges of side walls 52 to constitute'a rearward extension of casing F bracketing the support member C. Two of the three exposed sides of posts '34 and 36 are designed to cooperate with prismatic grooves cut into the opposite sides of said-bosses.

Two plates 64 and 66, secured by bolts 68 onto the longitudinal ends of bosses 6i and 62, are designed to cooperate with the third side of posts 34 and 36, thereby completing the guides for the, movable casing F..

From the above description it will be apparent that theuguides for the movable press portion are positioned on the four corners of a rectangle substantially coinciding with the contour of movable platen 50, and that these guides are located on the out-side of head D, whereby they can be proportioned sufl'iciently heavy to withstand the high stresses to which hydraulic presses are generally submitted, especially in the case of eccentric loading which occurs when the workpiece is set near the edges of plates 14 and 56.

Obviously, the above described guides are fitted, in known manner, with gibs allowing the adjustment and taking-up of backlash which occurs after a prolonged time of operation. 7

The press-platen assembly F is powered by hydraulic driving elements G, which partly extend inside the previously described head D as more fully explained herein after. C-frame support B has a box-shaped configuration and is formed by two plates16, 18 connected to transversely extending plates 29, 22 and also, as clearly seen in FIG. 4, to plates 28 and 39 of bracket D. The hydraulic drive means G of the press comprises a hydraulic cylinder 70 which extends through the hollow box-shaped head D and receives a piston 74 bearing upon platen 5t).

Another hydraulic cylinder 72 has its rain 76 extending through an opening 78 in the platen 50, the lower end of this ram being provided with a' bearing member 92 a which matingly fits into a bottom recess 93 of the platen whereby the latter may be hydraulically lifted. Members 16, 18, 2t 22 are rigid with a bracket 24 forming part of the C-frame B. The stationary bed 14 of base A is formed with reinforcing ribs 12 and a support plate 10. The posts 34, 36 are bridged by a web 44 having an access hole K. Transverse reinforcing members 49, 42 are provided between posts 34, 36 and plates 16, 18 of the supporting frame structure.

It is to be understood that the claimed protection ex tends also to the press featuring the guide system in question.

Obviously, many modifications and variations of the present invention are possible in the light of the above teachings. Therefore, it is to be understood that the invention is not limited in its application to the details specifically described or illustrated, and that within the scope of the appended claims it may be practised otherwise than as specifically described or illustrated.
